AUTOMACARA PORTAL PENTRU INTERVENȚIIPORTAL AUTOMACARA FOR INTERVENTIONS
Invenția se refera la o automacara portal pentru intervenții capabila sa funcționeze ca vehicul electric autonom, sa funcționeze ca macara portal, sa funcționeze ca incinta cu microclimat si sa se plieze in gabarit specific pentru transport rutier; toate funcțiile sunt obținute cu mecanisme specifice invenției pentru a putea funcționa in parametri optimi in afara suprafețelor amenajate si in condiții climaterice vitrege; poate fi folosita pentru intervenții rapide la utilaje sau vehicule grele, de orice natura, imobilizate la locul desfășurării activitatilor, prin defectare accidentala, sau in parcurile de utilaje si vehicule grele pentru manipulare de subansamble, inclusiv transportul in relația cu halelele de reparații, sau poate fi folosita ca mijloc de ridicat si transportat in halelele fara pod rulant.The invention relates to a portal crane for interventions capable of functioning as an autonomous electric vehicle, to function as a portal crane, to function as a microclimate enclosure and to be folded into a specific structure for road transport; all the functions are obtained with mechanisms specific to the invention in order to be able to operate in optimal parameters outside the landscaped surfaces and in vitreous climatic conditions; it can be used for rapid interventions on machinery or heavy vehicles, of any kind, immobilized at the place of the activities, by accidental failure, or in the parks of heavy machinery and vehicles for handling subassemblies, including transport in relation to the repair halls, or it can to be used as a lifting device and transported in the halls without a bridge.
In stadiul actual macaralele portal in majoritatea covârșitoare a cazurilor sunt macarale cu direcția impusa pe sine si in foarte puține cazuri sunt dotate cu cauciucuri si cu roti directoare;toate mecanismele de ridicare folosite in stadiul actual sunt mecanisme atașate pe grinda in exteriorul ei si fac parte din categoria cabluri înfășurate pe toba, acționate de un motor electric prin intermediul unui reductor, menținerea poziției sub sarcina fiind asigurata prin frane;sunt cunoscute brevete, ca de exemplu CN200951934, CN201817210, EP1873112, care reprezintă soluții tehnice specifice macaralelor portal pentru produse dedicate.In the present stage the portal cranes in the overwhelming majority of cases are cranes with the direction imposed on them and in very few cases they are equipped with tires and steering wheels; all the lifting mechanisms used in the present stage are mechanisms attached to the beam on its outside and are part of from the category of cables wrapped on the drum, driven by an electric motor through a gearbox, maintaining the position under the load being secured by brakes; patents are known, such as CN200951934, CN201817210, EP1873112, which represent technical solutions specific to portal cranes for dedicated products.
Dezavantajele sistemelor actuale sunt date de faptul ca versatilitatea macaralelor portal este scăzută întrucât in majoritatea covârșitoare a cazurilor pot îndeplini funcția de ridicare si de transport strict intr-o suprafața delimitată de distanta dintre picioarele de rezemare, pot funcționa numai pe suprafețe amenajate,respectiv cale de rulare metalica sau platforme betonate, toate mecanismele de acționare sunt expuse interperiilor si neprotejate la depunerile din atmosfera.The disadvantages of the current systems are due to the fact that the versatility of the portal cranes is low since in the overwhelming majority of cases they can perform the lifting and transport function strictly in an area delimited by the distance between the support legs, they can only work on landscaped surfaces, respectively metallic rolling or concrete platforms, all drive mechanisms are exposed to interpersions and unprotected to deposits in the atmosphere.
Invenția de fata elimina dezavantajele enumerate mai sus prin aceea ca propune un nou concept de utilaj de ridicat si transportat utilizabil in spatii deschise, ca alternativa pentru perechea de utilaje folosite in stadiul actual,respectiv automacara pentru ridicat si stivuitor pentru transportat. Pentru obținerea acestui deziderat automacaraua portal pentru intervenții este formata dintr-o construcție metalica de forma cadru portal pliabil dotat cu mijloace specifice invenției pentru a funcționa ca vehicul electric autonom, ca macaraThe present invention eliminates the disadvantages listed above by proposing a new concept of lifting and transporting equipment usable in open spaces, as an alternative to the pair of machines used at the present stage, respectively the lifting and lifting forklift trucks. In order to achieve this goal, the intervention portal automaker is made of a metal structure with a folding portal frame, equipped with specific means of the invention to function as an autonomous electric vehicle, as a crane.
